In Join Game's server browser a click selects a game, its row in the
yellow-outlined picture Custom Edition draws for it, and a click on the
selected game, a double click, A, Enter or JOIN joins it; one click
joined it before. The keys move the selection.
(cherry picked from commit 472d232246568ed2e3ee56bc93d97a3530feea54, without that fork's
Online Games screen; OpenCE's rows already take the focus only from a
click, not from the pointer passing over them)
